Support Solr 5, Solr 6

[dsolovay]

Task checklist:

• [x] Determine API for getting Solr information.
• [x] Query Solr info, get version
  • [x] If version >= 5.x, copy basic_configs/conf to new directory location.
  • [x] Copy and rename managed_schema to schema.xml
  • [x] If necessary, create data folder. I think Solr will do this automatically, but need to confirm.
  • [x] Fix configuration to <schemaFactory class="ClassicIndexSchemaFactory"/>, removing existing element.
  • [x] Remove AddSchemaFieldsUpdateProcessorFactory.
  • [x] Test with 4.10, 5.0, 6.3 and Sitecore 8.2, test 6.3 and Sitecore 8.1
  • [x] Update README

Works fine with 4.1 and 4.10

Moving this to Roadmap. 5.0 has a significantly different API (e.g cores are created from command line), and the distribution no longer ships with a "collection1". I'd like to see if there is a way to find out from the URL where the Solr file system is located, even if no core is loaded yet, Then I could implement a process similar to the one with 4.x, except that I will need to copy the conf file from server\solr\configsets\basic_configs\conf, and rename managed-schema as schema.xml. (Note: Solr 5.0.0 ships with schema.xml in the basic_configs\conf folder, but by 6.3.0 this has been renamed managed-schema.

Did some exploring of the Solr API, and you can access the version and path via http://localhost:8983/solr/admin/info/system.

With this in hand, we can query the Solr version, and if 5.0 or above, we can generate the instanceDir from the basic_configs directory.

As an interim step, throwing meaningful error if Solr 5:

Index creation appears to work with 5.0, but I am getting this error when I try to build the index:

ERROR: [doc=sitecore://master/{975ca216-d3ea-43a9-af69-964daab8bc11}?lang=da&ver=1&ndx=sitecore_master_index] unknown field 'name_t_da'

Receiving this error when rebuilding "sitecore_master_index" on Sitecore 8.2 with Solr 5.0.0:

And with 6.3.0, I get this error when rebuilding sitecore_master_index:

Looks like issue is this element:

<processor class="solr.AddSchemaFieldsUpdateProcessorFactory">

Thanks, Stack Overflow! http://stackoverflow.com/a/31721587/402949

Tested 8.1 against Solr 6.3, and 8.2 update 1 against Solr 4.10, Solr 5.0 and Solr 6.3. Testing consisted of rebuilding the sitecore_master_index and confirming that: (A) documents appeared in Solr, and (B) content editor search worked. I also rebuilt all indexes for the SC 8.2 + Solr 6.3 instance.

As noted in #41, Sitecore 8.0 is not working with Solr installation. This looks like a preexisting issue.
